Abstract (en)
[origin: EP2745949A1] Straightening machine (10) comprising a frame (12) supporting housings, each housing receiving a roll shafts (14) rotatable about its axis, the straightening machine being characterized in that it further comprises: - at least a first assembly (A1) comprising a first guide (66) defining a first convex surface and a first corresponding guided element (70) defining a first concave surface, said first surfaces contacting each other at a first contact surface (S1); - at least a second assembly (A2) comprising a second guide (68) defining a second convex surface and a second corresponding guided element (72) defining a second concave surface (S2), the second surfaces contacting each other at a second contact surface (S2), - means for rotating at least one roll shaft housing (22,26, 28,38, 90,92 98,), the rotation being guided by the assemblies about a virtual axis (P) transverse to the roll shaft axis X, to compensate bending due to straightening of a product.
